Mongolia’s Great Lakes Depression – November 12th, 200946.0N 105.0E
The lakes visible here in the Khyargas District of Mongolia’s Uvs Province are part of the same system interconnected lakes in the Great Lakes Depression.
The large, dark greenish blue lake at the top is Lake Khyargas, upon which the Khyargas Nuur National Park is based. This protected area was established in 2000 and covers about 3,328 km². It also includes the smaller, lighter green, freshwater Lake Airag, just south of Lake Khyargas.
In the lower left quadrant is Lake Khar-Us. Its area value of 1,852 km² includes the island Agbash (or Ak-Bashi, White Head) with an area of 274 km², so the water surface area is 1,578 km² only. Here, the island appears to almost separate the bright green western side of the lake from the brown right side. Primary inflow is the Khovd Gol river, which creates a large fan-shaped river delta on the western shores.
Finally, in the lower right quadrant are Lakes Khar and Dörgön. The waters of Lake Khar, above, appear green, while those of Lake Dörgön, below, appear dark blue.
